Wireless service providers may provide latitude and longitude through which technologies?

• A. Latitude only via handset.
• B. Altitude data through network-based tech.
• C. Address-based location data only.
• D. Latitude and longitude via handset-based and network-based technologies.

Answer: (D)

Latitude and longitude can come from two sources: the device itself and the network. The phone’s built-in GNSS receiver (GPS, GLONASS, Galileo, etc.) provides precise coordinates directly, which is handset-based positioning. The network can determine location using cell towers, timing information, and sometimes Wi‑Fi signals to estimate where the device is, even when GPS isn’t available or reliable; this is network-based positioning. Modern systems often blend both methods to improve accuracy, indoors or in urban canyons.

That’s why the best answer is that coordinates are provided through both handset-based and network-based technologies. The other options are incomplete because they ignore either the network-based capability, or they misstate what is typically reported (altitude or only an address), whereas precise latitude and longitude can be obtained from either or both approaches.
